Details of Disappearance

Smolinski was last seen on August 24, 2004 by his neighbor in Waterbury,
Connecticut around 3:30 or 3:45 p.m. Billy had been upset after arguing with
his girlfriend. He reportedly went to his neighbor's house and told the neighbor
he needed them to care for the dog because he would be gone for three days and
asked them to feed the dog who was locked inside the home. The neighbor said
Billy never returned with the keys to his house so they could care for the dog and
has not been heard from since.

Smolinski deposited most of his paycheck on August 23, 2004. There has been no
activity on his bank accounts.
Billy's keys and wallet were left inside his truck which
was also left behind.

According to the police records, as of August 2004, Smolinski had been involved in a yearlong relationship with his girlfriend, a Woodbridge school bus driver for
B&B Transportation.
During that same period of time, the girlfriend had also been involved with another man, also a Woodbridge school bus driver and a former member of the Board of Selectmen.
According to the police reports, the woman said that Smolinski broke off the relationship during the week preceding his disappearance when he learned about her relationship
with the other man.

The girlfriend admitted to tearing down Smolinski's missing person posters.

A close friend of the woman's son, who died in February 2005, said that the son choked Smolinski to death at the woman's apartment.
The body was buried at a construction site in Shelton; the grave site was covered with concrete the following day.

The woman told the police that Smolinski "was an outdoorsman and loved to hike in the woods, and he knew how to survive in the woods."

The investigation was taken over by the FBI in August 2006.
In May 2007, police and FBI agents dug behind a home on Fort Hill Avenue in Waterbury after a private investigator uncovered a tip in the police file.
The tip stated that Billy was murdered and buried on the property; however, the search did not uncover any evidence that he was located there.
Additional searches were performed on other yards in the area, as well as underneath the Route 8 overpass near Wharf Street.
